Title: Pipe joint
Inventor: FUKAE YASUO
IPC: F16L23/026
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent generation of stress concentration on a welded portion irrespective of fluctuation of padding form of fillet welding between an outer peripheral wall of an exhaust pipe and a flange. SOLUTION: An outer peripheral wall of an exhaust pipe 1 inserted into a through-hole 11 of a flange 10 is connected to the flange by fillet welding. A bead 2 is projected into the pipe within 2mm from an edge E of the welding padding at the proximity of welded part of the exhaust pipe. A base and a top of the bead 2 show smooth circular arc in their sections. It is thus possible to diffuse stress on the edge of the welded portion even when the padding is expanded in the projected shape, and prevent breakage of the welded portion.

Title: Rf-agc circuit of 1-system diversity tuner
Inventor: NISHIYAMA YOSHINORI
IPC: H04B7/08
Filed: 1984-09-13
Abstract: PURPOSE:To decrease the number of component parts and to attain the cost reduction in an RF.AGC circuit of a 1-system diversity tuner, by connecting a resistance to an antenna switch circuit to attenuate the high frequency gain in a conduction mode and energizing said resistance in a strong field mode. CONSTITUTION:The output of an RF.AGC terminal of a front end circuit 4 is set at an H level in a medium or weak field mode. While transistors TRQ1 and Q2 are kept ON and a resistance R3 is not energized. Thus the value of the current flowing through PIN diodes D1 and D2 is decided by resistances R1 and R2 only. In a strong field mode the output of the RF.AGC terminal of the circuit 4 is set an L level. Then the TRQ1 and Q2 are turned off and the R3 is energized. Thus the value of the current flowing through the diodes D1 and D2 is affected by the resistance R3. Then the high frequency gain of an antenna switch circuit is attenuated.

Title: Control system for main memory device
Inventor: GOTO TOSHIO
IPC: G06F12/00
Filed: 1985-08-30
Abstract: PURPOSE:To shortena memory access time by dividing the response signal from a main memory device to CPU into two, estimating the time from the releasing of clock stoppage of the CPU to the occurrence of clock for fetching the data and sending, first, the first response signal. CONSTITUTION:A main memory device 12 starts the action by the address sent from a main memory control device 11 and a memory access requesting signal SRVi.

Title: Sample cell
Inventor: AZUMA YOJI
IPC: G01N21/03
Filed: 1994-07-22
Abstract: PURPOSE:To obtain a sample cell which uses a sample gas in a small amount and whose sensitivity, reliability and durability are high by a structure wherein a gas container having the entrance and exit part of light whose reflection has been suppressed is provided inside the sample cell. CONSTITUTION:A gas container 13 which is to be filled with a sample gas is built in a sample cell 11. An optical beam comes in, and goes out from, the container 13 at a reflection factor of nearly zero. As a result, while the loss of light due to a reflection at this part is made nearly zero, the sample gas and concave mirrors 3 to 5 can be separated. Even when a corrosive gas or the like is to be measured, the mirrors 3 to 5, adjusting screws 6, 7 and the like are not corroded. In addition, since the container 13 can be formed easily to be a free shape as different from the concave mirrors, it can be formed in a thin rectangular shape to an extent that the backward and forward movement of the optical beam is not disturbed. In addition, since the container 13 is installed, a shielding material for an incident and radiating window part is not required, and it is possible to prevent the attenuation of light due to a reflection generated at the shielding material.

Title: Electro-conductive transfer recording sheet
Inventor: HAYASHI SEIICHI
IPC: B41J31/00
Filed: 1983-10-13
Abstract: PURPOSE:To prevent the generation of shavings by containing a specific amount of a solid lubricant having a specific average size in an electro-conductive resistance layer. CONSTITUTION:0.2-110wt% of a solid lubricant with an average particle size of 0.1-1.5mum is contained in the electro-conductive resistance layer 2 of an electro-conductive transfer recording sheet. As the solid lubricant, an inorg. compound such as graphite, molybdenum disulfide or tungsten disulfide or an org. compound such as polytetrafluoroethylene or polyacetal having an average particle size of 0.1-1.5mum is used. As the particle size of the solid lubricant becomes smaller and the dispersion thereof becomes more uniform, the generation of shavings from the resistance layer is reduced. In order to improve dispersibility, a binder resin such as polyacetal having a polar group or a vinyl chloride/ vinyl acetate resin is pref. used and each component constituting the resistance layer is applied to a support layer after dissolved or dispersed in a solvent. When thermal transfer recording is performed by a electro-conductive head, shavings of the resistance layer is reduced to a large extent and image speckles can be almost eliminated.

Title: Laser resonator
Inventor: YAMAGUCHI YUTAKA
IPC: B23K26/042
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a laser resonator, in which alignment is easy and aligning quantity can be remarkably decreased even if the attaching state of a returning mirror is changed, by constituting the returning mirror so as to have two reflecting surfaces forming a right angle. CONSTITUTION:Laser light repeats reflections between an output mirror 1 and a rear mirror 2 by way of a returning mirror 3b. Thus the laser light is amplified. Part of the light is transmitted through the output mirror 1 and taken out. Even if the returning mirror is deviated in the direction of alpha, incident light 4 and reflecting light 5 can always keep a parallel state. The reflecting light is slightly deviated by the deviation of the direction Y and the direction theta. The deviation is a parallel movement. Since the length of a light path is long, said devaition is minute and negligible in comparison with the deviation of angles. In the resonator using such a returning mirror, deformation in the direction does not affect the alignment of the laser, even if the attaching angle of the returning mirror is changed due to thermal effect and the like. Only the deformation in the direction beta is considered. Therefore, the attaching structure is simple and the change in alignment can be made small.
